RADIA TOR-BUSHING.

Specification of Letters Patent. Patented lylay 26, 1914,

Application filed June 16, 1911. Serial No. 633,465.

To all whom it may concern Be it known that we, SAMUEL J. WARNOOK andJOSEPH J. NEUMAN, cltlzens of the United States, residing at Chicago, inthe county of Cook and State of Illinois, and at Beaver Dam, in thecounty of Dodge and State of WVisconsin, respectively, have inventedcertain new and useful Improvements in Radiator-Bushings, of which thefollowing is a specification, reference being had to the accompanyingdrawing, forming a part thereof.

This invention relates more particularly to the supply and returnconnections for hot water radiators.

Its main objects are to facilitate makin such connections; to admit ofthe use .0 standard fittings, unions, valves and elbows for the supplyand return connections; to make both connections with the radiator closetogether near the floor, thus avoiding cumbersome, inconvenient andunsightly connections with the upper part or with different. parts of aradiator; to admit of removing and replacing defective parts of eitherconnection, valve, union or elbow without loss of other parts; andgenerally to improve the construction and operation of devices of thisclass.

It consists in the construction, arrangement and combination of parts ashereinafter particularly described and defined in the appended claim.

In the accompanying drawing like characters designate the same parts inthe several figures.

Figure 1 is an outer end elevation of the bushing in connection with thelower part of a. radiator section and supply and return connections asthey are assembled in practice; Fig. 2 is a horizontal section on theline 2 2, Fig. 1; Fig. 3 is a side elevation of the bushing; and Fig. 4is an inner end eleva tion thereof.

The bushing constituting the. principal feature of the invention,consists of an externally threaded collar (1, which is fitted into thestandard threaded opening in the lower part of one of the end sectlons bof a radiator. It is formed at the outer end with a squared orpolygonal'wreneh head 0, to facilitate its insertion in and removal fromthe radiator section, and has two horizontally diverging internallythreaded branches 0? and e for the standard supply and returnconnections of the radiator.

Hot water radiator sections are usually made with openings of the samestandard size in opposite sides .of the lower' parts thereof, forconnecting" the sections in the usual manner with nipples, and one ofthese openings in the outer side of one of the end sections serves formaking the supply and return connections by means of the bushingwhichconstitutes the principal feature of the present invention. Thesebushings are therefore made with collars of the same size and threadedto fit the standard opening in any radiator section. The convergingendsof the coupling nipples point directly into the threaded part of thecollar, their threaded parts lying within the area of the wrench headthereof. They are also made with branches of difi'erent sizesforstandard pipe and fittings used with hot water radiators for makingthe supply and return connections.

' A partition, preferablyv arranged horizontally, divides the collarinto upper and lower passages, and at the outer end is so twisted thatthe upper passage communicates with an inlet pipe, 9, and the lower Ipassage communicates with an outlet, h, the

inlet and outlet being both in the same hori-' zontal plane. At itsinner end the partition f is curved or bent upwardly so as to deflectand direct the inflowing hot current of water upwardly into the upperpart of the radiator and thus separate it froin and prevent itsinterfering with the outflowing current of cold water which is deflectedand directed thereby into the outlet passage h. The free and eifectivecirculation of water through the radiator is thus promoted.

Gouplin nipples a are threaded in the branches controlling the supply ofhot water to the radiator is detachably connected with the nipple of thesupply branch ol by a coupling collar lo, while a standard elbow Z isdetachably connected with the other nipple in like manner, by a collar70. The supply and reand e, and a standard valve j for turn pipes m andn are threaded respectively 7 in the case of valve y and in the elbow Z,leading downwardly therefrom arallel wlth each other and close to theradiator through the floor near which the supply and return connectionswith the radiator are made.

The branches (1 and e of the bushing point obliquely out from thecollar, and at such an angle to each'other that the supply and return'pipes m and n are separated sufficiently to allow for the usual floorplates 0 being placed around the pipes to cover the openings therefor inthe floor without interference, as shown in Figs. 1 and 2.

A small opening 7), as shown in Fig. 4, is made through the wall of thebushing between the inner and larger end of the inlet passage 9 and theouter and smaller end of the outlet passage 71., to prevent the radiatorfrom becoming air bound.

By the employment of a bushing constructed as herein shown anddescribed, the standard fittings, valves, elbows, couplings and pipesemployed in the ordinary manner with hot water radiators may be used inmaking the supply and return connections through the same opening at oneend of a radiator, and in case a valve or any other part of thesefittings is defective, it can be removed and replaced without loss ofother parts, as in that class of fittings in which the valve or valvecase is formed integrally with the return connection, thereby avoidinginconvenience not only in installing but also in repairing theconnections of hot water radiators, besides effecting a saving inexpense. p

It will be seen that the device of our, invention, embodies in a singleintegral structure, a radiator bushing having independent supply andreturn passages together with branches so disposed that the usualfittings of the valve supply pipe and the return pipe,

" can be em loyed. Furthermore, by reason the bushing by the horizontalpartition and of the horlzontal disposition of the axes of the branchesand the bore of the bushing, we

are able to provide a bushing which presents a symmetrical andneatappearance such as is necessary in an attachment of this character.The accomplishment of this object is partly due to the 'fact that theaxes of the two branches and of the bore are horizontally disposed anddivision of the supply and return water is efi'ected in the bore of inthe branches, by the vertically disposed partitions, one of which servesto close one branch to one passage, and the other of which serves toclose the other branch to the remaining passage. 55.

Combined with all these. advantages we provide a bushing which does notextend inwardly into the 1m terior of the radiator section, and which 7has a partition which does extend into the interior of the radiatorsection substantially completely across the zone of ingress and egressto and from the bushing so as to most effectively divide the supply andreturn flows. By reason of thefact that the axes of the bore and thebranches are horizontally disposed, and also by reason of the fact thatWe provide horizontal and vertical partitions, we are able to provideadischarge for the supply branch which exceeds the cross section of thesupply branch itself, and likewise, we are able to provide an intakearea or. passage for the return branch which exceeds in cross section,the cross section of the return branch. Thus no choking or retarding ofthe flow'is possible either from the supplybranch or to the returnbranch.

Various changes in details of construction of the device may be madeWithout materially .afl'iecting its operation or departing from theprinciple of the invention.

We claim:

In combination, a hollow radiator section having a threaded opening, abushing having a main boreand a threaded portion adapted to be turnedinto but not extending appreciably inwardly beyond the inner end of thethreaded opening,zsaid bushing having substantially horizontallydisposed supply and return branches diverging substantiallyhorizontallyfrom the longitudinal axis of the bushing bore and a substantiallyhorizontal partition dividing said bore into upper and, lower passagesfora portion of the length of said bore and projecting beyond thebushing into the hollow radiator section substantially completely acrosssaid hollow radiator section, said' bushing having upper and lowervertically disposed partitions extending substantially longitudinally ofsaid bore for a portion of their length and diverging inoppositedirections substantially transversely of the longitudinal axis of thebore to close the return branch to the upper passage formed by saidhorizontal partition and to close the supply branch to the lower passageformed by said horizontal partition, the cross section of eachpassageexceeding the cross section of the respective branch with which itcommunicates and the axes of the branches and said bushing beinghorizontally disposed.
